cfLikeDislike is a Chrome extension developed by 08developer that allows users of Codeforces, a competitive programming website, to easily like or dislike problems from the problem set. With this extension, users can express their preference for a particular problem with just a click.

One of the main features of cfLikeDislike is the ability to see the number of users who have liked or disliked a problem. This information can be valuable for users who want to gauge the popularity or difficulty of a specific problem. By providing this data, the extension helps users make informed decisions about which problems to tackle.

The cfLikeDislike extension is a valuable addition to the Codeforces experience, allowing users to interact with the problem set in a new and engaging way. Whether you want to show your appreciation for a well-designed problem or express your dislike for a particularly challenging one, cfLikeDislike makes it easy to have your say.
